What is what does it mean when a guy turns back to look at you?

As an AI language model, I don't have personal experiences but I will give general information.

When a guy turns back to look at you, it could mean multiple things. It could be that he finds you physically attractive and is trying to catch a better glimpse of you. He may be curious about you or find you intriguing in some way. He could also be trying to make eye contact with you, to gauge your interest and see if you're looking back at him. In some cases, a guy may be looking at something or someone else, and his glance toward you could be coincidental. However, if he consistently looks back at you, it could be a sign that he's interested in getting to know you better.
